CN203107887U - Cardiovascular radiography pushing injector - Google Patents

Abstract

The utility model belongs to the field of medical tools, and particularly relates to a cardiovascular radiography pushing injector. The cardiovascular radiography pushing injector comprises an injection tube, a needle head, a core rod and a handle at the tail end of the core rod. A hemispheric base is arranged on the bottom portion of the injection tube, a connecting block is arranged between the hemispheric base and the injection tube, a clamping groove is formed in the bottom portion of the connecting block, the hemispheric base is installed inside the clamping groove, the handle is arc-shaped, an annular baffle is arranged on an end portion of the injection tube, and the inner side of the annular baffle is arc-shaped. Through the technical scheme, when injection is conducted on a patient, an injection process is enabled to be stable, contrast medium leakage is avoided, and accordingly an examination result is not affected. The arrangement of the arc-shaped handle and the annular baffle can increase stressed area, and aching feeling during operation of medical staff is lessened.

Description

The angiocardiography injector

Technical field

This utility model relates to a kind of angiocardiography injector, belongs to the medical tool field.

Background technology

In the therapeutic process of cardiovascular disease, in order accurately to understand the situation of patient's blood vessel, usually contrast agent is injected blood vessel by injector and carry out angiography, employed radiography injector is similar with ordinary syringe clinically at present, the handle of core bar is very little, add the contrast agent thickness, the medical worker is when injecting contrast agent like this, and the lifting surface area of hands is little, the time slightly length will cause palm pain discomfort, and syringe rocks easily during operation, thereby make the syringe needle displacement, contrast agent leaks outside, and influences diagnoses and treatment, though at present a lot of injector are improved handle and syringe, effect is relatively poor.

The utility model content

The technical problems to be solved in the utility model is: provide a kind of simple in structure, can make injection process stable, and can alleviate the angiocardiography injector of medical worker's palm sense of discomfort.

Angiocardiography injector described in the utility model, the handle that comprises syringe, syringe needle, core bar and core bar end, the syringe bottom arranges domed base, between domed base and the syringe contiguous block is set, the contiguous block bottom arranges draw-in groove, and domed base is installed in the draw-in groove, and handle is curved handle, there is ring baffle the syringe end, and the inboard of ring baffle is set to arc.

The domed base contact surface is big, can play the stable support effect; Contiguous block be used for to connect syringe and domed base, and syringe is installed on the domed base, can be when the medical worker operates not only can be laborsaving but also can make injection process stable, syringe needle is not rocked, check effect thereby improve; Domed base is installed in the draw-in groove, changes easily, and adjustable angle, and is easy to use, and the material of domed base can select for use relatively than soft material matter, makes convenient adjustment, and do not injure patient; The ring baffle of curved handle and arc can increase lifting surface area, the pain when the minimizing medical worker operates.

The thickness of domed base is 3mm～6mm.Can make simple in structure, easily operation.

The beneficial effects of the utility model are:

Simple in structure, realize that easily this utility model is by above scheme, when giving patient injection, can make injection process stable, avoid contrast agent to leak outside and influence check result, the setting of curved handle and ring baffle can increase lifting surface area, alleviates the pain of medical worker when operating.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, syringe needle 2, syringe 3, contiguous block 4, ring baffle 5, handle 6, core bar 7, domed base 8, draw-in groove.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described further:

As shown in Figure 1, angiocardiography injector described in the utility model, comprise the handle 5 of syringe 2, syringe needle 1, core bar 6 and core bar 6 ends, syringe 2 bottoms arrange domed base 7, between domed base 7 and the syringe 2 contiguous block 3 are set, contiguous block 3 bottoms arrange draw-in groove 8, domed base 7 is installed in the draw-in groove 8, and handle 5 is curved handle, and there is ring baffle 4 syringe 2 ends, the inboard of ring baffle 4 is set to arc, and the thickness of domed base 7 is 4mm.

During use, domed base 7 is placed on patient's arm, regulates injection angles by draw-in groove 8, syringe needle 1 is inserted patient's blood vessel inject and get final product.

Claims (2)

1. angiocardiography injector, comprise the handle (5) that syringe (2), syringe needle (1), core bar (6) and core bar (6) are terminal, it is characterized in that: syringe (2) bottom arranges domed base (7), between domed base (7) and the syringe (2) contiguous block (3) is set, contiguous block (3) bottom arranges draw-in groove (8), domed base (7) is installed in the draw-in groove (8), handle (5) is curved handle, there is ring baffle (4) syringe (2) end, and the inboard of ring baffle (4) is set to arc.
